Patented Mar. 10, 1942 UNITED STATES PATENT OFFICE MULTIPLE, ROLLING MACHINE James J. Ingels, Chicago, Ill.

Application June 19, 1939, Serial No. 279,948 r 6 Claims. (01. 153-2) An object of this invention is to provide an improved form of sheet rolling machine adapted to roll simultaneously, or at different times, two or more strips of sheet metal.

Anther object is the provision of an improved form of drive for such a multiple rolling machine. Still another object is to provide a firm yet yielding frame for the forming rolls so that sheet metal can be rolled thereby from thirty gage to eighteen gage. Another object is the provision of means for automatically feeding sheets along predetermined paths so that they enter theforming rolls in a uniform manner.

These and other objects as will hereinafter appear are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawings, in which- Figures 1 and 2 are perspective views of one embodiment of the multiple rolling machine;

Fig. 3 is an enlarged vertical longitudinal view on the line 33 of Fig. 1

Fig. 17 is a partial section on the line 11-41 of Fig. 16.

The embodiment illustrated is designed particularly for simultaneously rolling a drive cleat IA as shown in section at the left of Fig. 15

and a lock B 0, commonly known to the trade given separate numbers.

as a Pittsburgh lock, at the right hand side of this figure. The machine consists essentially of a bed frame or base 20 supported upon suitable legs 2|. and having secured thereover a floating frame or head 22. The head and base are provided with registering openings, preferably four in number, adapted to receive guide or leader pins 23 which have heads upon one end, while the opposite end is screw-threaded to receive locking nuts or the lik 25 under which are placed compression springs 24. These leader pins are accurately ground to fit the registering openings in the base and head so that the movement of the head with respect to the base, as

will later be described, is substantially a parallel one.

Substantially in line with the leader pins are adjusting screws 26 which are adapted to bear upon the upper surface of the base so as normally to maintain the head a fixed distance from the base in opposition to the movement produced by the compression of the springs 24. Looking nuts 21 are provided for these adjusting screws. The forming rolls for forming the sheet metal and the shafts upon which they are mounted are carried by the base and head and these will now be described. The several pairs of shafts as shown on the lines 5-5, 6-6, l'!, 9--3 and |0-l0 of Fig. 3 are substantial duplicates so that a description of one pair as that shown in Fig. 12 will serve for the other pairs of shafts. For clearance, however, these several shafts will be Shafts 30, 3| appear on section 5--5; shafts 32,33 are on sections 6--6 and ,|2l2; shafts 34,, 35 are on section 'l-l; shafts 36, 31 are on section 9-9; and shafts 38, 39 are on section Ill-l0.

Shafts 30, 3| are driven in opposite directions and at equal. speeds by means of similar meshing gears 40, 4| keyed thereon; shafts 32, 33 are similarly driven by meshing gears 42, 43; shafts 34,

35 by gears 44, 45; shafts 36, 31 by gears 46, 41; andshafts 38, 39 by gears 48, 49. gears 40 and 42 is placed an idler gear 50 which rotates upon a suitable stud 5|; similarly an idler 52 is placed between the gears 42 and 44; an idler gear 53 is likewise placed between the gears 44 and 4B; and another idler 54 between the gears 46 and 48.

This train of gears is driven in any suitable manner as by means of a motor (Fig. 1) driven through a suitable gear reduction to a shaft 6| upon. which is keyed a gear 62 which meshes with gears 63 and 64 which in turn mesh.re spectively with gears 42 and 46.

Between the r Referring now to Fig. 12, the shaft 32 is suitably journaled, preferably at four points, in the base 20 while the shaft 33 is likewise journaled in the head 22. Fig. 6 shows the same arrangement of forming rolls and meshing gears, as that of Fig. 12, but with the shafts, base and head of Fig. 4; the rolls I4, 15 of Fig. 7 bend the strip g to the form N, which remains the same in Fig. 8. The rolls I6, 11 of Fig. 9 close the strip-to the and I35 which connect withshafts I36 and m by means of couplings I38, I39. The outer ends of these shafts are journaled in suitable bearings in an end member I40 which is carried by a frame MI to which it is secured by suitable bolts I42, I43, the inner end of the frame being secured to the base 20 as by means of bolts M4.

7 The outer end of the frame MI may be supported form A of Fig. 9; and the rolls I8, Iii-complete the operation by closing the strip to the: form for use. a Figs. 4 and 5; the rolls 92, 93 form the edge 13 the-rolls 94, 95 form the edge B';' an idler roller 96' (Fig. 8) bends the edgeinwardly to theipo'sition 13 the rolls 9?, es of Fig. 9:bend the'edge unto the position B and the rollers 99, I00 complete the Pittsburgh lockas shown at 13 (Fig. 1D) e In Fig. 1 1 is fshow n the'use o'f both the 'cleat A and of the Pittsburgh lock-B Thus the cle'at A is used to lock twoabutting :sheets II and -l02,'both of which have their edges bent backasshown at I63 and IE4, these-bent back edges-beingheldfirmly within the cleat which is applied by driving it endwise over these bent back edges thereby firmly securing the sheets Hit and IM together in substantially the same plane.

"sheetC similar to the sheet Bis-passed twice through the rolls SE-to' I 00 inclusive' with'the result that Pittsburgh locks of the type B are formed on each' of-its edges. This is done by passing one edge of thesheet through these-rolls, then turning the sheet around andpassing the other edge throu'gh the same rolls so as to form the same "lockYo'n both edges. The sheet 102 hasit's-edge turned up atright angles as shown at IIIS (Fig. 1 1) so as to fitunder the-overhanging-portion :er' thePittsburgh lock. The outer portion IB'B is'then bent up from the dotted line position to the full line position so as to firmly lock the sheet 1 02 to the sheet C.

' 1 Referring now to Figs. 1, 2 and l i, the strip A is'fd int-o the machine byhandbetween the guides-H 5], III. 'As-itis pushed-forward, it passes under 'thetucker rolls H2, H3 which are jiournaled upon suitable stub-axles on a frame I I4 1 which is secured to thebase by means of bolts I I5. These tucker rolls are set at a slight angle toward the guide I II and have their edges knurled so that-asthe sheet is fed forward, it will be held against the guide III until the strip is caught'bythe-first set of forming rolls. After that, the rollspreservethisalignment. Similarly the sheet B passes'u'nder similar tucker rolls H6; H1 which urge the sheet against a longi 'tudin'al'guide H8 which also serves to holdjthis sheet with it is cut by the first forming rolls. Theim'pression made upon the :sheet serves to gii-idethat sheet from that point on through thesucceeding rolls until it comes out under a guide 119 (Fig. 15). I

In Figs. 16- and l? is shown an attachment for forming a Pittsburgh lock on one edgeofa sheet B and for simultaneously slitting that sheet so as'to s'e'ver a she'et l'j 'therefrom. In order to "do this, the shafts "3'4 "and have extensions I34 A in which condition the driving strip is ready 1 The rolls 9|], 9| form the edge B of' c as by means of a leg I IE'secured thereto by means of bolts I 45. Slitter rolls l5fl, i5] are adjustably secured on the shafts I34, I35 at any desired point so as to provide a sheet B (Fig. 16) of a desired width. 7

Thus it will be seen that a very simple and -eihcient means is provided for forming any desired edge on one side of a sheet and simultaneously slitting the sheet to a desired width. This greatly speeds up the Whole forming operation, reduces the number of handlings of the sheet, and also reduces the amount of machineryrnecessary to perform these various operations.

.tA third' setof -rolls-may be added as shown in Fig. 12. Thus the formin'g 'roll shafts, ass; and 33, (Fig. 112), maybextendd to receive e third set of'formingrolls' as I66, I61 of a series to form say a flange and lock of still another form from that previously described. The -forms of rolls illustrated areYeXemplifications only. Any suit able. edge forming rolls may be used.

It will be readily observed upon inspection of Fig. 3 that the head irameZZ isvsup'ported on the base'frame zfli-th'atiit may readily yield verticallyi'n opposition to the springs 24 While the adjusting screws 26 effect a predetermined minimum spacing between the frames as well as the forming rolls "carried 'b'y the shafts. Furthermore, such predetermined minimum spacing may spaced bearings as is more clearly illustrated in Fig. .12. Such construction provides for the mounting i'of. the 'Efo'rming 'rol ls between adjacent bearingsthe drivinglgea'rs between theinner- :most bearings and if desired other forming rolls externally "of the i'trames adjacent certain of the bearings. This provides-a well balanced construction as :well :as providing suffieient resistance to bending or*deforrnation of theshaft as -may be occasioned in prior construction having substantial 'd'istances between adjacent bearings. I claim:
